We're dividing 78698907 by 140 
We want to figure out the number of times 78698907 can be divided by 140.

Moving on to step 1:
140 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 140

Let's proceed to step 2:
78 divided by 140 is 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 140

Going ahead to step 3:
If we divide 786 by 140, we get 5 and a remainder of 86.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 700 from 786, we get 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 140

Let's proceed to step 4:
869 divided by 140 is 6 with a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
Subtract 840 from 869 to get 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 140

On to step 5:
140 can be fit into 298 2 times, resulting in a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 562.0
Deduct 280 from 298 and we're left with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 140

Let's proceed to step 6:
140 goes into 189 1 times with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 5621.0
If we subtract 140 from 189, we get 49.
Take the next digit (0) from the dividend and append it to 49, then repeat: 490 / 140

Moving on to step 7:
When dividing 490 by 140, we get 3 with a remainder of 70.
The number 3 becomes the next digit in our result. 
Result so far: 56213.0
Subtracting 420 from 490 leaves us with 70.
Include the next digit (7) from the dividend after 70, then repeat: 707 / 140

On to step 8:
When dividing 707 by 140, we get 5 with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 562135.0
The remainder is 7 after subtracting 700 from 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
140 can be fit into 70 0 times, resulting in a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 562135.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
If we divide 700 by 140, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 562135.05
Subtract 700 from 700 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
140 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 562135.05
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
140 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 562135.05
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 562135.05 with a remainder of 0.0.
